Go forward to the back of the planning room. There is a door that can be opened with a Torque Bar. One you see it, Inside is a Weapon part and tons of supplies. There is a bench right behind you if you need to construct one.

Now, out the door next to the bench, and out the next door until you are outside. Go catch up to your friends. Looks like you are getting attacked by some men. take out the handful of soldiers here, then continue through one of the buildings. There are some supplies here. The next door takes you outside. Ride the cargo elevator down, and prepare for getting attacked. Fight your way across the gap and continue into the next building. There's a weapon part, suit upgrade station, and some supplies in this room.

Advance out the back door and fight your way past these guys. Follow the cart rails in the snow to the next building, where to the right you'll find an Alient Artifact, and go in. Once the door is open, go through the next room with a creature hanging from the ceiling. Once you go down the ladder, look through the ladder to see a few glowing dots. Use Kinesis on them to find a new weapon part.

Move on through the next door. Fight your way across the next expanse, then tuck into the next open door. Fight through the next room, what looks like an excavation site. There is a new enemy here, a small thing that crawls into heads and takes over people. Fight through them, and out the door. There are more of them out here too, so kill them all off. The next door has to be unlocked with a mini-game.

Continue past the recently-unlocked door, and you open up in the Conning Platform. Walk to the right and find a weapon part. Power up the generator to open the gate to the next area as well as to power up the bench behind you. There is a giant drill that is blocking your path.

Use Kinesis to lower the safety walls, which will send the drill into the arena you are in. Use Stasis on the drill, then shoot out the big yellow bulbs on the interior of the drill. The first bulb you blow will stop the drill for a few seconds, then start it back up. The drill will get more and more erratic. After two bulbs have gone, the drill will stop for a few moments, and then start again on its side. I found this open enough to use Stasis and then blow both of the remaining bulbs at once. Oh, by the way, you'll get attacked by several necromorphs to keep you busy.

After stopping the drill, advance forward into the next area and take the cargo elevator up. There is a S.C.A.F. artifact behind a pillar out here. Through the door into the next building, you find your friends and a massive alien.
